Another reason to oppose that childish fence

In case you were running out of reasons to lambast the proposed fence along the US-Mexico border, here's another:

Environmentalists and U.S. Fish and Wildlife Service wardens say the barrier would disrupt the migration of scores of species from jaguars to hawks and humming birds along a wildlife corridor linking northern Mexico and the U.S. southwest known as the "Sky Islands."

The chain of 40 mountain ranges links the northern range of tropical species such as the jaguar and the parrot in the Mexican Sierra Madre Mountains, and the southern limit of temperate animals such as the black bear and the Mexican wolf in the U.S. Rocky Mountains.

"Bisecting the area with an impermeable barrier such as a double reinforced wall or fence could really have a devastating effect on these species," said Matt Skroch, a wildlife biologist and executive director of the environmental non-profit group Sky Island Alliance in Tucson, Arizona.

"If they build it, we could really say goodbye to the future of jaguars in the United States," he added.

As one commenter noted, the only thing the fence won't keep out is illegal immigrants.
